PHILLIP STOVALL, OF NEWNAN, GEORGIA.

IMPROVEMENT IN WATER-WHEELS.

Specification forming part of Letters Patent No. 210,164, dated November 19, 1878; application filed September 21, 187B.

To all whom it may concern:

Be it known that I, PHEJLIP STovALL, of

Newnan, in the county'of Coweta and State of Georgia, have invented a new and valuable Improvement in Water-Wheels; and I do hereby declare thatthe following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specication, and to the letters of reference marked thereon. A

Figure l of the drawings is arepresentation of an interior plan of my water-wheel; and Fig. 2 is a side view, part sectional, of the same.

My invention relates to water-wheels; and consists in the improvements in the construction of the same hereinafter fully described, and particularly pointed out in the claim.

Referring to the drawings, A represents the bottom flange with draft-tube and supportv for the Wheel cast upon the bottom side. B represents the tangential guides, formed into feed-apertures in the usual manner. C represents the dome with a flange at the bottom, between which and the iange A the guides are secured.

In one side of the dome is cast a chamber, D, or recess, and this recess receives the gearpinion L.

E represents the cover of the dome, and through it pass the shafts of both the pinion L and-the water-Wheel. Itigidly with the cover of the dome, and extending downward therein, is a post, F, provided on its surface with a spiral groove, f, or quick-screw on opposite sides thereof, which grooves receive pins or studs I on the inner surface of the gatecylinder I.

The gate K is cylindrical in form, and has radial arms 7c. extending from the gate-cylinder to a circumferential toothed band, n, which j y forms the upper periphery ot' the gate. 'Ilie pinion L gears with the gear-wheel n.

K is an ordinary central-discharge waterwheel. The gate K, when closed, passes down between the water-wheel and the points of the guides B.

What I claim as new, and desire to secure by Letters Patent, is

The gate K, having gear n, spirally-grooved post F f, pinion L, and studs I, housed within the dome O, above the water-wheel, in combinationv with the said dome and water-wheel K', and with the chutes formed by the parts A B and flange on dome O, as and for the purpose set forth.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.

Il-IILLIP STOVALL.
